What is the difference between CAT5 and Level 5? I know that there is
CAT5, 5e, 6, etc but I've never heard of Level 5... Can someone
explain?

I've looked through my reference guides, but did not find anything on Level
5. I assume that this is in referrence to a physical cabling standard like
Cat5?

The "Level" rating refers to a rating system developed by Anixter (world's
largest distributor of communication/cabling
products)..(http://www.anixter.com)

It is basically a guide for companies buying/installing cable systems
looking beyond manufacturer hype (this was especially important during a
period when the standards groups were not providing much guidance and
cabling manufacturers were coming out with extended performance cabling
(some of the performance claims were complete bullshit)).

With the advent of Category 5e and very little networking hardware needing
performance beyond Category 5e (for now), the need for the Anixter Levels
program has somewhat diminished. However, if you're looking beyond Category
5e then cabling certified to an Anixter level might be an important
consideration. (Anixter levels have quite rigorous performance
specifications and testing)

I thought that Cat 6 was official now, but I did buy some cables marked
as Cat 6 about 7 years ago, well before Cat 6. (It was for a school
project, and I don't remember exactly what grade the kids were in.)

The only Level 5 I know of is http://level5.com/ , though you may be
talking about some level of CAT5 certification testing with a handheld
tester...

For instance, Fluke talks about Level IV as part of an IEC spec at
